My 5 year old son has had dizzy head episodes for about 6 months. This time started yesterday but he was still able to play and eat. This morning it seemed worse...but he ate breakfast. He has vomited once and said things were fuzzy and saw rainbows. About a month ago he woke up vomiting and with a dizzy head again...he had two minor blows to his temple the day before so I took him in and they did a CAT scan and everything was fine. In light of today I feel like it is more related to this on going dizziness. As his mother I have had classic migraines since a very young age...and am concerned that this is an early start to migraines. He is an other wise very healthy child...no ear infections as a younger child etc. He is 100% on the growth chart in height and weight as well.
